External Validity in Research Studies

What is necessary for a study to generalize its findings to a population?

What does ecological validity refer to in a study?

In generalization mode, researchers aim to:

Which statement best describes theory-testing mode?

Which is not a component of ensuring external validity in research?

Why might some studies not need to be generalizable to many people?

What is the importance of specifying the population of interest in a study?

Cultural psychology primarily examines how which context affects individuals?

External Validity in Research Studies

To generalize findings, a study needs a probability sample drawn from the target population.
Defining the specific population of interest is crucial for generalization.
A representative sample, not just a large one, is needed for proper generalization of findings.
A probability sample is essential for generalizing to a larger population.

Generalizing to Other Settings

Ecological validity assesses the study's similarity to real-world settings.
Research should use random samples from diverse populations (gender, age, ethnicity, socioeconomic status).
Socioeconomic factors, regions, and countries must be considered when generalizing.

Theory Testing vs. Generalization Mode

Theory testing mode prioritizes internal validity over external validity.
Theory testing aims to investigate associations or causal relationships.
Generalization mode prioritizes generalizability of findings to a wider population, which can also consider other contexts.

Cultural Considerations

Cultural psychology examines how culture shapes thoughts, feelings, and behaviors.
Researchers might adapt studies in real-world settings based on cultural contexts.

Real-World vs. Lab Settings

Field settings (real-world contexts) and lab studies are equally valid, if done well.
Experimental realism in a lab environment can create authentic experiences similar to real-world contexts.

This quiz explores the concept of external validity in research studies, emphasizing the importance of probability sampling and representative samples. It covers key factors that impact the generalization of findings, including ecological validity and the distinction between theory testing and generalization modes.
